Hi, I bought my horseradish plant as a baby from Bunnings for about $3.50. Second season now and I have about 7 plants in the one spot and it's GROWING... Wish I had have read that it takes over BEFORE I planted it in the ground!

Margaret, I haven't found the perfect time, the size of the leaves don't tell me anything. Last week I did use some, just scraping away surrounding soil and seeing the thickness of the root helped, the root was fairly thick, about the same as two fingers plus a little more. Getting it out is the hard part, the roots go down a long way so I cut the amount I needed and replaced the soil. Be careful if you do this because the root is very strong, a serrated knife worked o.k
